A lenticular is an image that appears differently depending on how you look at it. I created a particular sheet called the lenticular image displayed by moving the gaze from a side to another. In this case, I displayed it on a laptop for testing on it. I used to play toys like this when a kid. Here below is a reference how the lenticular works.
I wrote code for adjusting width of a vertical line and used templates to finish those bcz I usually need every single frame to animate a image under the plastic sheet.
